The Eisfeld Museum, located in the castle, displays evidence of Eisfeld's town history and regional folklore. Hidden behind the walls of Eisfeld Castle is one of the most extensive collections of Thuringian porcelain from 1760 to the present day. German idioms are explained simply and ingeniously using museum objects.

The Eisfeld Museum also includes the Otto Ludwig Poet Memorial for the poet born in Eisfeld in 1813 and the Inner German Border Memorial - Eisfeld-Rottenbach border crossing, which are also well worth a visit.
